Is it cool to add flour to pasta sauce, or is that a no-go?

[AL_]

Is adding flour to pasta sauce a good idea for thickening it, or should I avoid it? What do you guys think?

I don't recommend adding flour to pasta sauce since it can alter the flavor and give it a pasty texture.

Avoid adding flour; it can make the sauce gritty. Use a bit of pasta water or simmer the sauce longer to thicken it instead.
